Add water, truck says no thanks

[Rebelliousw0n]

Ok so almost a year an a half ago I was forced to park the truck due to the birth of my son. Just before parking it I had been working it too hard to keep up with fixing everything. Left it parked with nothing but water in the cooling system (was towing a tractor and overheated so filled with h2o for quick get home fix). I drained the radiator recently and cleaned everything up nice. Went to fill it back up and the truck says "no thank you" via the vicinity of the oil filter. how far should I dig? Or is it even worth it should I just start looking for a new block? Thanks guys.

My guess is the oil cooler. Try resealing it and see if the leak goes away.

Could be a crack block if it froze! use some coolant dye and a black light!

okay so an update on this problem. I pulled the oil cooler, replaced the seals (they fell apart when i pulled it apart). put it back on buttoned everything back up and added water again. i have been able to identify that its pouring out of this hole (see picture) by the oil cooler.




Call me stupid but i have no idea what that hole is for. any ideas? from what i can tell without tearing things apart more is im probably screwed. what you guys thing?

I'm not positive, but isn't that a freeze plug hole?
You should be able to buy a replacement at Napa

Looks like you lost a freeze plug

it also looks like the block is cracked at the freeze plug

[Rebelliousw0n]

where do you see that?

ah, that's just a flake in the rust layer. from what i can tell there is no external damage to the block.
